Want to build your own tool?
EgoCX specializes in custom software development. If you need a solution tailored to your brand or workflow, we can build it together. You can even build it yourself using our CMS.
Beyond the tools: a philosophy of making
Every tool in this directory has a story.
Some were born from frustration—a repetitive task that no existing solution handled well.
Others emerged from curiosity—a question like "what if this existed?" that refused to go away.
A few were built for a specific client project and then generalised because they were too useful to keep hidden.
This is how EgoCX works: we build things because we need them, and then we share them because others might need them too.
It's a simple cycle, but it's one that has shaped everything we do.
What unites all these tools?
Privacy by default. None of these applications send your data anywhere. Everything runs in your browser. When you upload a font to fffontum, it stays on your machine. When you generate content with JSON Content Factory, the API keys and prompts never leave your browser. When you manage domains with dddom, your data never touches our servers. This isn't a marketing claim—it's an architectural decision baked into every line of code.
Single-file simplicity. Most of our tools are a single HTML file with embedded CSS and JavaScript. You can download them, run them offline, carry them on a USB stick, or host them on your own server. No dependencies, no package managers, no installation rituals. Just a file that works.
Practicality over polish. We care about design, but we care more about whether the tool actually solves the problem you have. Sometimes that means a utilitarian interface. Sometimes it means a slightly quirky name (we have a soft spot for wordplay). But it always means that the tool exists because someone needed it—and that someone is usually us.
The Egosystem™ connection
These tools don't exist in isolation.
They are part of a larger ecosystem that includes EgoCX domains, Google Cloud services, AI assistants, and the CCContinue CMS.
The software you see here often starts as an internal utility that we use ourselves, and then we polish it enough to share with the world.
For example, dddom was built because we were managing dozens of domains across multiple clients and needed a simple way to track expirations without logging into a dozen different registrars.
fffontum started as a quick script to test fonts for client branding projects—then we realized that every designer we knew was using the same clumsy workflows, so we turned it into a full tool.
JSON Content Factory was born from a single question: "What if we could parallelize API calls using multiple keys?"—and it turned into a production-grade content engine that agencies and publishers now rely on.
Who are these tools for?
The short answer: anyone who works with text, data, or digital identity.
The longer answer: these tools are for the freelancer who needs to generate 50 product descriptions in an afternoon. For the domain investor who wants to track 200 expirations without spreadsheet fatigue. For the designer who is tired of uploading fonts to questionable third-party services just to see how they render in a headline. For the developer who needs to parse a large JSON response quickly. For the blogger who wants to turn their browser history into a research document. For the content manager who needs to check CSV files without opening Excel.
They are for people who value their time, their privacy, and their independence from bloated, subscription-based software.
The naming philosophy
You'll notice that many of our tools have unconventional names: FFFuck, NNNotige, Catch'em, Dulcat, lllines.
This is deliberate. We believe that tools should be memorable, not just functional.
A name that makes you smile is a name you'll remember. And a tool you remember is a tool you'll actually use.
The names are also designed to be searchable and distinctive—you won't confuse fffontum with any other font tool on the market.
What about support and updates?
These are living tools. We maintain them, fix bugs, and add features as we encounter new needs.
We don't have a formal roadmap because the roadmap is driven by what we're working on at any given moment.
If something breaks, we fix it. If a tool is missing a feature you need, we'd rather hear about it than guess.
We also believe in radical transparency. Every tool is what you see—there are no hidden data collection mechanisms, no analytics trackers, no "phone home" features.
You can open the browser's developer console and see exactly what the tool is doing.
This is not a compromise; it's a commitment.
Build your own tool
One of the most frequent questions we get is: "Can you build something like this for my specific use case?"
The answer is almost always yes.
EgoCX offers custom software development services for brands, agencies, and individuals who need a tailored solution that doesn't exist off the shelf.
Maybe you need a specialized content generator for your niche. Maybe you need a dashboard that combines data from multiple sources. Maybe you need a tool that automates a workflow that currently takes hours.
Whatever it is, we've been building custom software for over two decades, and we know how to turn a vague idea into a working tool.
Explore, experiment, enjoy
We invite you to poke around. Try the tools. Break them (in a safe way). Use them for real projects, not just demos.
The best feedback comes from someone who actually depends on a tool to get work done.
And if you build something with our software—a brand, a content strategy, a domain portfolio, a design system—we'd love to hear about it.
That's the whole point: tools that enable creation, not tools that replace it.
Start exploring the applications above. Each one has a story, a purpose, and a person behind it. That person is us. And we'd be happy to build something for you too.
